Characterization of recycled perfluorosulfonic acid membrane for a circular hydrogen economy
Perfluorinated sulfonic-acid (PFSA) ionomers, such as Nafion introduced by DuPont >50 years ago, are a superior class of ion-conducting polymers used in fuel cells and electrolysers due to their remarkable ion conductivity and chemical and mechanical stability. Fuel cell lifetime is, however, curtailed by chemical and physical degradation of the PFSA in the electrode and electrolyte membrane (amongst other mechanisms), which lead to unusable end of life cells. Furthermore, with increased adoption of sustainable energy technologies, increased demand for PFSAs is forecast. This translates into the necessity to recycle membrane components. Here we intend to study the water dynamics in degraded and recycled Nafion, as well as compare these to pure recast Nafion.
